I have the following problem and I am not sure how to fix it or if its a bug.
When setting an editor widget of a field to "External Resource" I can not access the widget from within the attribute table. When double clicking it, it shows the current path and the "..." button but I can't click on the button nor change the path manually (see the first screenshot). While accessing the same editor widget via the identify tool works fine (see the second screenshot).
Can I set the widget in some way so it works also while accessing it via attribute table or am I supposed to use the form in identify tool?
I am aware of the option, that I can set the view of the attribute table to "Form view" but this is not an option for my case.
Set up: Windows 10 64 bit with QGIS 2.14.15. I also checked that the "Editable" Checkmark is set.
